In this experiment, the risk-taking propensity of 90 inner city drug users was measured using a repeated measures test called the Behavioral Analogue Risk Task (BART; Lejuez et al., 2002). The higher the BART score, the higher the risk-taking propensity. Participants also filled out questionnaires so that their Psychopathic Personality Inventory (PPI) scores could be computed. PPI scores are used to detect psychopathic traits in a covert manner and are a common indicator of one's level of psychopathy. The main goal of the experiment was to examine the relationship between risk-taking (measured by BART) based on one's level of psychopathy (measured by PPI on a scale of 0–100), gender (1 for male and 2 for female), and heroin use (1 for heroin use and 0 for no heroin use). Below is a partial output of a multiple regression analysis.

Question: What is the response variable in this study?
Answer:
Correct option:
BART score
Explanation:
The Response Variable in a study is the variable of interest to the
researcher.The researcher studies the effect on the response
variable by changing the independent variables. Here the BART score
( Behavioral Analogue Risk Task) is studied by varying Gender,
heroin, and PPI.
